What Lao Zhou said is right, as long as the six most famous features of Ru Kiln porcelain are imitated, the imitation of Ru Kiln porcelain is almost complete.
As for the main characteristics of Ru porcelain, Chen Wenzhe knows it even more clearly.
The "green as the sky" that Chen Wenzhe just mentioned is one of them.
The glaze color is just like the sky clears after the rain, when the clouds clear and the fog disperses, the overall glaze color is calm and elegant, with a refined and refined texture. How can you imitate these characteristics?
Before today, Chen Wenzhe really didn't have any confidence.
But now it's different, he really has some confidence.
Of course, if he actually sees a Ru kiln ware and lets him see its past, it may be easier to copy it.
It's a pity, how rare is a piece of Ru kiln? Only true antique lovers know.
"Let's not talk about the sky blue color for now, let's talk about other features first. If you want to imitate Ru kiln, you must start with simple features!" Lao Li was still working hard, and the more he talked, the more excited he became.
Of course, Chen Wenzhe didn't make too much concessions either.
He just thought about it and became a little excited. He seemed to have passed the level?
Apart from the azure color, how many difficulties are there for him to imitate Ru kiln?
Face like jade? Is this easy to copy?
The glaze is moist and soft, as pure as jade, and is praised as "juicy and lustrous, dripping with water, like a paste, soluble in fat but not flowing, thick and sound like a chime, bright but not dazzling".
This is the glaze characteristic of Ru kiln porcelain, but this feature is really not difficult to imitate as long as you find the right materials.
Because when Chen Wenzhe was studying Longquan glaze before, he had studied the firing of celadon from the Song Dynasty.
The glaze of Longquan celadon has very obvious characteristics because its use of glaze is very special.
Generally speaking, the Northern Song Dynasty used lime glaze, and the Southern Song Dynasty used lime alkali glaze. The former had a thin glaze, while the latter had a thick glaze.
Pink green glaze is the latter, which can achieve a jade-like effect.
This is also reflected in the Ru kiln. For example, the glaze is like silk, warm and simple, bright and translucent, and the glaze is like piles of fat. It is quiet and elegant, and looks like green peaks. It has the meaning of "like jade, but not jade, but
It has the reputation of "better than jade".
The glaze is as soluble as paste but does not flow. The glaze is thick and sounds like a chime, which indicates that it is definitely not a thin glaze. This was quite special during the Northern Song Dynasty.
After all, celadon works in the Northern Song Dynasty generally had thin glazes, and only in the Southern Song Dynasty did they become thin and thick glazes.
Chen Wenzhe has studied these thoroughly, especially the changes in glazes.
Chen Wenzhe can make many porcelains. If you want to find one that is the best, it must be celadon!
The glaze is azure in color and the texture is like jade. This is the characteristic that he has grasped most accurately.
With this kind of technology, it is not difficult to replicate the glaze texture and glaze color changes of Ru kiln porcelain in the Northern Song Dynasty.
The second is "morning stars are rare", which means there are only a few bubbles in the glaze like morning stars. The glaze of your kiln is thick, but there are a few bubbles in the glaze when exposed to light.
As mentioned before, if the glaze is too thick, when making porcelain, the water under the glaze layer will not evaporate easily when it is dried in the shade.
Even when fired in the kiln, if the glaze is too thick, it will block water evaporation. At this time, water vapor will remain under the glaze layer, or in the glaze layer, forming bubbles.
Chen Wenzhe has been able to create this feature for a long time, so it is naturally not a difficulty.
Let's talk about "incense ash body", which means that the body color of Ru kiln porcelain is fragrant gray, similar to the color of incense ash after burning, and the texture is pure and delicate.
Needless to say, this must be related to purple gold soil. When studying the Longquan kiln, Chen Wenzhe also studied it clearly.
He knows a lot about the clay used in Ru kiln porcelain.
Calculating it this way, how difficult is it to bake Ru kiln? Sesame nails?
Generally, coarse porcelain needs to be stacked when firing, and the feet cannot be glazed, so the bottom circle is rough.
The Ru kiln is naturally different. "The sesame nails are full of glaze." This is the characteristic of the sesame nails of the Ru kiln. That is, the feet are covered with glaze, and the soles of the feet are supported by pins as thin as sesame dots for firing.
This does not bother Chen Wenzhe, he would have known it long ago!
And at the end, there is the "cicada's wing pattern", which is a pattern with fine fragments in the enamel texture.
The opening generally shows tiny openings like cicada wings. This opening phenomenon is caused by the different expansion coefficients of the porcelain body and the enamel.
He can also do it, but when firing, the effect of opening the film can only depend on God's will.
With such a stroke, Chen Wenzhe discovered that he could actually do it?
It turns out that the most rare thing is to be as blue as the sky, and he also has a new look today.
He can actually do the jade-like face, cicada wing pattern, bubbles, fragrant gray tire, and sesame nails on the back!
Celadon is as good as jade. Chen Wenzhe has been able to do this for a long time, and he has done it very well.
Qing Rutian just found the clue, and the incense ash body comes from porcelain clay, so it should be no problem to use purple gold clay.
Morning star dilution is the control of glaze moisture, which Chen Wenzhe has already studied.
He had already learned how to make sesame nails, and today, thanks to the generous teachings of the two old men, he took a step further and gained greater confidence in the success of firing.
In this way, what are the difficulties for him to imitate Ru kiln?
It seems that there is only a problem of tiny cracks in the enamel texture!
If you think about it carefully, the most difficult thing is actually starting the film, because this factor is uncontrollable.
Now that a problem has been discovered, it must be solved, so with a little guidance, Chen Wenzhe introduced the focus of communication into the opening of porcelain.
Chen Wenzhe gave a little guidance, but unexpectedly the two old men really understood it very well.
As soon as he heard the explanation, Chen Wenzhe understood that Jingzhen had a long tradition. Even after the firing of Ru kiln porcelain was lost, they had copied it in various dynasties in the later period.
Of course, even if they are not specifically imitating Ru kiln, there are many other kilns who have learned Ru kiln's techniques, and even kilns such as Ge Kiln have also spread the cutting technology.
Cracking is a natural cracking phenomenon on the porcelain glaze. There are two reasons for its formation.
First, the clay extends in a certain direction during molding, which affects the arrangement of molecules;
Second, the expansion coefficients of the blanks and glazes are different. The shrinkage rate of the glaze layer is large when cooling after firing, so cracking is originally a shortcoming in porcelain firing;
During the Northern Song Dynasty, craftsmen at major kilns mastered the laws of cracking, and the split glaze (i.e., cracked glaze) produced became a special decoration for porcelain.
Ru, Guan, and Ge kilns in the Song Dynasty all had this kind of product.
The products of Ge kiln in Song Dynasty are the most famous. Chen Wenzhe also fired Ge kiln, but he had never fired it before.
If we really want to count, he knows Di Yao better because he has received inheritance in this area.
If we talk about film openings, then the most classic film opening is the ice crackle.
According to the color, there are eel blood, gold wire and light yellow caviar pattern.
According to the shape, it can be divided into mesh pattern, plum pattern, fine broken pattern, etc.
If there are lines on the surface of porcelain, it is called "opening".
It is divided into "large opening piece" and "small opening piece".
Small pieces of fine pieces are called "roe patterns";
The large and sparse ones are called "cow hair pattern", "willow leaf pattern" and "crab claw pattern", which are all used to describe its shape.
